ABOUT BARIUM CARBONATE
Barium carbonate (BaCO3), also known as witherite,is a white heavy powder , slightly soluble in water containing carbon dioxide. Hardly solve in water,is a chemical compound .
It is named after William Withering, who in 1784 recognized it to be chemically distinct from barytes. It occurs in veins of lead ore at Hexham in Northumberland, Alston in Cumbria, Anglezarke, near Chorley in Lancashire and a few other localities.
It is readily altered to barium sulfate by the action of water containing calcium sulfate in solution and crystals are therefore frequently encrusted with barytes. It is the chief source of barium salts and is mined in considerable amounts in Northumberland.
